camisole is a secure online judge for code compilation and execution. You give some untrusted source code and a test suite, and camisole compiles the code and runs it against the test suite.
It uses isolate as a backend to safely compile and execute source codes using Linux kernel features such as namespaces, cgroups, chroot and resources limits.
The full documentation of Camisole, including installation instructions and usage examples, is available at https://camisole.prologin.org
- Built-in support for a wide variety of languages, including Ada, C, C#, C++, Haskell, Java, JavaScript, Lua, OCaml, Pascal, Perl, PHP, Python, Ruby, Scheme…
- Isolation: camisole runs both the compilation and execution stages in a sandboxed environment provided by isolate
- Limitation of resources (time, wall-time, memory…)
- Simple HTTP + JSON or MessagePack interface
camisole is used through a simple HTTP/JSON interface. Sending a program is as simple as that:
$ curl -s localhost:42920/run -d '{"lang": "python", "source": "print(42)"}' | python -m json.tool
